Product: High-Quality Nickel-Based Alloy Welding Wire
Alloys: Incoloy 800HT (N08811), Incoloy 825 (N08825 / 2.4858)
1. What are the primary applications of this nickel-based welding wire?
Answer: This welding wire is used for joining nickel-based alloys in high-temperature, corrosive, or chemical environments. Typical applications include chemical processing plants, petrochemical equipment, power generation, heat exchangers, and furnace components. Alloy 825 is especially suitable for acidic or chloride-rich environments, while 800HT is ideal for high-temperature structural applications.
2. What is the difference between Incoloy 800HT and Incoloy 825 welding wire?
Answer:
Incoloy 800HT: High carbon variant of Incoloy 800, providing increased strength and creep resistance at elevated temperatures.
Incoloy 825: Contains molybdenum and copper, offering superior resistance to reducing and oxidizing acids, chlorides, and other corrosive media.
3. Which welding processes are compatible with these wires?
Answer: The wires are suitable for Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), and Shielded Metal Arc Welding (SMAW) when used with proper shielding gas and procedures. They ensure strong, corrosion-resistant joints with Incoloy base metals.
4. What mechanical and chemical properties should customers expect?
Answer:
Chemical composition: Conforms to UNS N08811 (800HT) and N08825 (825 / 2.4858) standards.
Mechanical properties: High tensile strength, excellent ductility, good creep resistance at elevated temperatures.
These properties ensure welded joints maintain structural integrity under thermal and corrosive stress.
5. How should the welding wire be stored and handled?
Answer:
Keep in a dry, controlled environment to prevent oxidation and contamination.
Store in original sealed packaging until use.
Avoid direct contact with hands or dirty surfaces to prevent contamination that may affect weld quality.
